RE: [Xen-users] Running Xen 2.0 for Counter Strike: Source

["John Cianfarani" <jcianfarani@xxxxxxxxxx>]

Why not just recompile the kernels to use 1000hz? I did this to get
another application to work better under xen.

I changed all the values to 1000hz in the following files

./linux-2.6.12-xenU/include/asm-xen/asm/param.h
./xen/include/asm-x86/config.h

Thanks
John

Subject: [Xen-users] Running Xen 2.0 for Counter Strike: Source

I'm running Xen on a dual xeon system at the moment and somehow the
results are a bit less than what i expected. I've started to do some
monitoring on it to see how bad it is. you can see for yourself on:
http://core.zokahn.com/cs-01/

I've installed Xen 2.0 using the howto in howtoforge:
http://www.howtoforge.com/perfect_xen_setup_debian_ubuntu

This virtual machine is running 2 counter-strike public servers. Games
has
always been a fine benchmark tool :-) The fps number should be much
higher. On my home server (a single p4 running lots and lots of stuff)
the
reading is 150-200 average untweaked with basic settings.

In the counter strike forums there is word about the kernel hz. They say
the kernel should be configured to 1000hz. fortunately the used
2.6.11.12
kernel has a standard setting of 1000hz. As you can see in the kernel
source: include/i386/param.h. However current readings in cs are more
like
hz is set to 250!

Can I expect this to be the same in xen 3.0? Is the default 1000hz 
changed by the Xen patches for the client kernels? Is there any way to
tweak Xen for use with Counter-Strike?

Kind regards,

Bart
